摘要： PURPOSE: Slag generated from the ironmaking/steelmaking process of an iron mill has been under stern supervision due to heavy metals. Especially, stainless slag has been limited in their usage because chrome oxides is contained in the stainless slag. Thus, it become an essential condition that environmental contamination causable from elution reaction of chrome ion should be carefully monitored before the stainless slag is used as structural aggregate. At present, several solidification methods such as cement solidification and plasma-assisted solidification that is generally applied to field to prevent heavy metal elution from stainless slag have been developed, however plasma-assisted solidification that is considered the most effective method to engineers has demerit in that its operation cost is relatively high and costly equipment. CONSTITUTION: A slag generated in the steelmaking process is blended with red clay in a blending ratio of 3:7 to 1:1 and then the mixture is heat treated in the temperature range of 1150 to 1250deg.C for 30-90min. Stainless slag that is solidified by the present method can be applied to the manufacture of tile or brick.
摘要翻译：目的：炼铁/炼钢工艺生产的炉渣由于重金属受到严格的监督。特别是，不锈钢渣的使用受到限制，因为不锈钢渣中含有氧化铬。因此，在不锈钢用作结构骨料之前，应该仔细监测铬离子的洗脱反应引起的环境污染的基本条件。目前，已经开发了一些通常适用于现场以防止重金属从不锈钢渣中洗脱的水泥固化和等离子体辅助固化的凝固方法，然而等离子体辅助凝固被认为是工程师最有效的方法，其运营成本相对较高，成本高昂的设备。构成：在炼钢过程中产生的炉渣以3：7〜1：1的混合比与红土混合，然后将混合物在1150〜1250℃的温度范围内热处理30-90分钟。通过本方法固化的不锈钢渣可以应用于瓷砖或砖的制造。

摘要： PURPOSE: An aging method of electric furnace slag with hot carbonated water is provided to perform efficient aging by depositing electric furnace slag into hot carbonated water. CONSTITUTION: Electric furnace slag is aged by a method of depositing the slag into hot water spraying carbon dioxide gas. The gas uses carbon dioxide or waste gas containing carbon dioxide. The electric furnace slag is aged in the hot carbonated water by introducing the carbon dioxide and waste gas. The CaO(calcium oxide) of the electric furnace slag reacts with water to generate Ca(OH)2. The CA(OH)2 reacts with carbon dioxide and changed into the CaCO2. Therefore, the CaO is promoted to gush out and the surface of the electric furnace slag is neutralized to stabilize expansion.
